DISPENSING-TANK.

Specification of Letters Patent.

Patented Dec. 28, 1909.

T 0 all whom it may concern:

Be it known that I, Moms ZWIRMAN, a citizen of Roumania, and residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Dispensing- Tanks, of which the following is a specification.

The invention relates to dispensing tanks and particularly to those for use with oil or other liquids wherein it is desired to accurately measure or gage the amount of liquid which is withdrawn from time to time. The invention has for its principal objects; the provision of an improved tank of this character having measuring means which may be conveniently operated; and the provision of improved and simplified valve controlling means for regulating the flow of liquid from the series of measuring cans employed and the admission of air thereto. The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective View of the tank with the casing broken away in order to disclose the parts inclosed thereby.

Figure 2 is an enlarged detail section through one of the cont-rolling valves, and

Figure 3 is a section through the valve taken on the line IIIIII of Figure 2.

As shown in Figure 1 the main body portion of the tank comprises a casing A of sheet metal mounted upon the legs B and carrying intermediate its ends the bottom portion C, the casing below such bottom serving merely as a protector or shield for the measuring cans and controlling mechanism to be hereinafter described. The tank is filled through an opening D in the top of the tank. Beneath the bottom of the tank C is the series of fiat measuring cans E, F and G placed one beneath the other, and connected by means of the pipes H and I. An outlet K is provided leading from the bottom can G and carrying the faucet L upon the outside of the casing A. The upper can E is connected to the tank by means of the pipe M, and a series of controlling valves N, O and P are located in the pipes M, H and I. These controlling valves are all precisely the same in construction and are provided with handles Q extending through the casing A just above the faucet I).

The construction of the controlling valves will be clear from Figures 2 and 3, wherein enlarged sections through the valves are shown. The device comprises a casing 1 and a hollow rotary valve 2 carrying the handle Q. The valve is held in position by means of the nut 3, and is provided intermediate its ends with the inlet *port 4, the outlet port 5, and the air port 6, which ports are adapted to register with the inlet passage '7 of the casing, the outlet passage 8 of the casing, and the air passage 9 through the casing (Figure 3). A small air pipe 10 is secured in each air passage 9 and extends upwardly a short distance as indicated in Figure 1. The valve as illustrated in F igures 2 and 3 is in open position. In order to turn it to closed position it is moved a quarter of a revolution in the direction inclicated by the arrows, the stop 11 on the valve taking against the stop 12 on the casing (Figure Another stop 11 limits the reverse movement. When in this closed position the passage 7 will be cut off, the air port 6 will register with the passage 8, and the port 5 will register with the air passage 9.

In the particular embodiment of the invention illustrated, the capacity of the cans E, F and G is respectively slightly less than two quarts, one quart and one quart, the apparatus being designed to measure of either one quart, two quarts or a gallon depending upon which of the handles Q is operated. The quantity of liquid contained in the connecting pipes is suiiicient to bring the quantity contained in the cans up to full measure. The handles Q are normally in such position that the valves are open, as illustrated in Figures 2 and 3, and the cans E, F and G are filled from the tank, the faucet L being of course closed. If it is now desired to draw off a gallon of liquid the upper handle Q is operated thus turning the plug or valve in the top valve N ninety degrees. As heretofore explained this movement of the valve closes the inlet 7 of the casing, places the port 6 in com munication with the outlet 8, and places the port 5 in communication with the air passage 9. If now the faucet IJ be opened all. of the fluid in the three cans E, F and G is drawn off, as the valves 0 and P are open and communication between the upper can E and the tank is closed. The fluid flows out freely from the cans E, F and G for the reason that the air pipe 10 is placed in communication with the upper can E and air is thus permitted to flow in freely to take the place of the fluid as it is withdrawn. After all the liquid is withdrawn the faucet L is closed, and the handle Q of the upper valve N turned so as to open the valve and permit the three cans to fill up again. If it were desired to draw off a single quart of the liquid the valve P would be closed, thus shutting off communication with the upper cans E and F and opening communication between the air pipe 10 and the can G, so that on the opening of the faucet L the oil in the can G might be readily withdrawn.

The cans E, F and G are preferably made in the flat form illustrated in order to reduce the necessary length of the casing A from the bottom of the tank to the bottom of the casing, and also in order that the handles Q may be brought as close as possible together, and into proximity to the faucet L, so that all of these parts are within convenient reach of the operator. The use of the short air pipes 10 prevents any accidental slopping out of the oil when the valve is closed. The lower portion of the casing A serves to conceal the measuring devices, and protects them from injury, and furthermore adds to the general appearance of the tank. The valves illustrated are simple and cheap in construction, and as will be apparent from the description heretofore they serve the dual function of controlling the flow of oil and the inlet of air to the can beneath when the valve closed, thus doing away with the necessity of two independent valves, such as might otherwise be necessary for accomplishing this function. The whole apparatus may be constructed very cheaply, and not only gives accurate measuring, but also accomplishes this result by means of a simple construction little liable to get out of order.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following 1. In combination, a tank; a plurality of measuring cans in series, one beneath the other below the bottom of the tank; an outlet from the bottom can provided with a valve; passages from the tank to the upper can and from each other can to the'can above it; and a controlling means for each passage comprising a valve casing provided with a transverse passage and with an air 2. In combination, a tank; a plurality of measuring cans in series, one beneaththe other, below the bottom of the tank; an out- 4 let from the bottom can provided with a valve; passages from the tank to the upper; can and from each can to the can above it;

and a controlling means for each passage,

comprising a casing 1 having an inlet 7, an outlet 8, and an air port 9, and a rotary hole low valve 2 mounted in the casing and pro vided with an inlet port 4:,an outlet port 5, and an air port 6, all of said ports .inthe valve communicating with the interior of.

the valve and with each other. 7

3. In combination, a tank; a measuring can-G therebeneath provided with an outlet K and valve L; a passage from the tank to the can; and controlling means for regu lating the flow to and from the can comprising a casing 1. having an inlet 7 an out let 8, and an air port 9, and a rotary hollow valve 2 mounted in the casing and provided with an inlet port 4, an outlet. port 5, and an air port 6, all of the said ports in the valve communicating with the interior of the valve and with each other. 7

i In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
